Abstract

We have used ellipsometric measurements on solutions of 2-dihexylamino-7-dicyanomethylidene-3,4,4a,5,6-pentahydronaphthalene and related polyenes in liquid 9-(2′-ethylhexyl)carbazole to measure the electric-field-induced birefringence at wavelengths of 690 nm and 830 nm. This electric-field-induced birefringence is related to the product of dipole moment squared and the polarizability anisotropy, μ²Δα, and to a large extent determines the dye's photorefractive figure-of-merit (FOM). We show that μ²Δα increases with the conjugation length and report one of the highest μ²Δα values observed so far.
